摘要：
Embodiments of the present invention pertain to antimicrobial glass compositions, glasses and articles. The articles include a glass, which may include a glass phase and a cuprite phase. In other embodiments, the glasses include as plurality of Cu1+ ions, a degradable phase including B2O3, P2O5 and K2O and a durable phase including SiO2. Other embodiments include glasses having a plurality of Cu1+ ions disposed on the surface of the glass and in the glass network and/or the glass matrix. The articles may also include a polymer. The glasses and articles disclosed herein exhibit a 2 log reduction or greater in a concentration of at least one of Staphylococcus aureus, Enterobacter aerogenes, Pseudomomas aeruginosa bacteria, Methicillin Resistant Staphylococcus aureus, and E. coli, under the EPA Test Method for Efficacy of Copper Alloy as a Sanitizer testing conditions and under Modified JIS Z 2801 for Bacteria testing conditions. In some embodiments, the glass and articles exhibit a 2 log reduction or greater in a concentration of Murine Norovirus under Modified JIS Z 2801 Test for Viruses testing conditions.本發明之實施例係關於抗微生物玻璃組成分、玻璃及製品。製品包括玻璃,玻璃可包括玻璃相及赤銅相。在其他實施例中,玻璃包括複數個Cu1+離子,包括B2O3、P2O5及K2O的可降解相,及包括SiO2的耐久相。其他實施例包括具有複數個Cu1+離子安置於玻璃之表面上及玻璃網狀結構及/或玻璃基質中的玻璃。製品亦可包括聚合物。在針對以銅合金作為Sanitizer測試條件的功效的EPA測試方法及針對細菌測試條件的改進JIS Z 2801下,本文所揭示之玻璃及製品在金黃色葡萄球菌(Staphylococcus aureus)、產氣腸桿菌(Enterobacter aerogenes)、綠膿桿菌細菌(Pseudomomas aeruginosa bacteria)、耐甲氧西林金黃色葡萄球菌(Methicillin Resistant Staphylococcus aureus)及大腸桿菌(E.coli)之至少一者的濃度方面展現出2個或更大的對數降低。在一些實施例中,在針對病毒測試條件之改進JIS Z 2801測試下,玻璃及製品在小鼠諾羅病毒(Murine Norovirus)之濃度方面展現出2個或更大的對數降低。
